Excavator Compactor Stabilizing Lever and Vertical Drive Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing add-on compactors for narrow ditches and pits are not robust enough to maintain precision and even compaction, and their design often makes them too wide for use in very small spaces.
Innovation Solution
The add-on compactor features a tilt-resistant design with a connecting arm and stabilizing lever between the upper and lower parts, a compact arrangement of the imbalance generator and hydraulic drive, and a robust yet space-saving kinematic connection using a belt and rubber-metal buffers, allowing for precise positioning and effective compaction without increasing width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the add-on compactor is designed to be robust to withstand excavator loads, then it can maintain structural integrity and stability, but its width increases making it unsuitable for very small ditches and crevices
Solution Approach 1:
The patent redistributes components vertically instead of horizontally. The imbalance generator and hydraulic drive are arranged one above the other, utilizing the vertical dimension to accommodate robust components without increasing the horizontal width, thus maintaining suitability for narrow spaces while ensuring structural integrity
2Length of moving object
If the add-on compactor uses a narrow design to fit small ditches, then it can access tight spaces, but the lower part becomes prone to tilting relative to the upper part, reducing compaction precision
Solution Approach 1:
The patent introduces a stabilizing lever that acts as a counterbalancing mechanism. This lever, combined with the connecting arm, creates a stabilizing moment that counteracts tilting forces, allowing the narrow compactor design to maintain stability and precision during operation
3Reliability
If the add-on compactor uses a complex hydraulic drive system to ensure reliable operation, then it can maintain consistent compaction performance, but the device complexity and width increase
Solution Approach 1:
The patent integrates the hydraulic drive components directly into the lower part structure, merging the drive system with the compactor body. This integration reduces the number of separate components and connections, simplifying the overall system while maintaining reliable hydraulic operation through direct mounting and reduced leakage paths

Function Achieved in This Case
This design ensures a more even and effective compaction result while maintaining a narrow profile, allowing the compactor to be used in very small ditches and crevices without tilting, and is compatible with conventional excavators.

AI summary
The cultivation compressor has an upper part (12) for coupling on an excavator arm and a lower part (14) with an unbalance generator. A connecting device (62) connects the upper part with the lower part in elastic moving direction. A fixed connecting arm (52) is arranged on the lower part extending upto the upper part. The fixed connecting arm is connected with the upper part by another connecting device (70) at a height, which lies in vertical operating position at a distance (D) over the former connecting device.
